DRIER.

Application led July 30, 1924. Serial No. 729,097,

To all 'whom it may concern:

Be it known that I, VVTLLTAM ALLINsoN,

a citizen of the United States, and av resident of Des Moines, in the county of Polk and State of Iowa, have'invented a certain new and useful- Drier, of which the follo\v ing is a'specification.

The objectof my invention is to provide a drier of the tumbler typ' used in laundries and other places.

More particularly, it is my obj-ect to provide a drier of the kind mentioned of simple, durable and inexpensive construction.

A further object is to provide such a drier having a reversible rotating drum or the like and means for supplying heated air thereto and drawing heated air therefrom, whereby the air passing the tumbler or rotating drum remainssubstantially at atmos heric pressure.

ore particularly, in this connection, it is my purpose to provide in such a structure a tumbler arranged within a casing, means for forcing heated air into the casing, and means for drawing air ,from the casing.

A further object is to provide in such a machine means for regulatingthe flow of air, so as to-permit air to be moved simul taneously through the tumbler casing from the atmosphere and from a heater and for regulating the relative amounts of heated and fresh air. v

With these and other objects in view, my invention consists inthe construction, arrangement and combination of thevarious parts of my drier, whereby the objects con-.

templated are attained, as hereinafter more fully set forth, pointed out in my'claims, and illustrated in the accompanying .drawings, in which:v

Figure .1: shows aperspective view of a drier embodying my invention, parts being broken away.

Figure v2 shows a horizontal, sectional 45, view through 'the fans or pumps. Y Fi re 3 shows a vertical, sectionalV view through the drier, taken'from front to rear substantially at the middle of the drier; and

'compartments for fans or. pumps.

tion or wall 18, connecting the end walls Generally speaking, my structure involves a compartment in which are mounted the rotating drum or tumbler, a compartment for steam heating pipes or the like, and The general arrangement is such that air may be forced by a fan through the heater compartment and thence throughthe tumbler compartment, and is also suoli that one or more of the fans may be used for pulling the air :from the tumbler compartment.

In the, accompanying drawings, I have used the reference numeral 10 to indicate generally the side walls of the device. The side walls are connected at the rear of the device by a rear wall 11 and at the top and bottom by a top wall 12 and bottom wall 13 respectively.

, At the front of the device, a wall 14 is inclined downwardly and forwardly from the top 12, as shown.

From the lower edge of the inclined wall member 14, there extends downwardly a wall member 15 in which is a door 16.

-From the lower edge `of vthe wall portion 15, a casing or compartment member or wall 17 ,extends downwardly and rearwardly to the bottom wall 13, The heater compartment and the tumbler compartment are separated by means of a connecting parti- 10 and inclined from its upper end near the top of the device, but spaced from the top 12 downwardly and rearwardly as shown. l

` Another partition member 19 extends from the lower edge of the wall or partition 18 downwardly and forwardly to the bottom wall 12.4

A horizontal artition or wall 2O extends from the partition 19, as shown in Figure 3, rearwardly to the vrear wall -11 and extendsfrom side to side in the machine.

' It will thus beseen that there is provided by the walls 10, 12, 14, 15, 17 18 and 19 a compartment A for the tumblers. There is rovided by the'walls 10, 11, 12, 18, 19, an 20 'a compartment Bfor the heating coils, and by the walls 10, 11, 13, 19 and 20v a compartment C for the fans.

The compartment C is divided into three sub-compartmentsby vertical partitions, 21 .l l6

d such compartments being at C1, C2 and C3 in Figure 2, the latter compartments being those provided for the fans and fan casings.

A horizontal shaft 23 extends through the compartment C and the sub-compartments C1, C2 and C3, as shown in Figures 1, 2 andV 3, projecting from the main casing and having on one of its outer-ends a gearing device, such for instance as the pulley 24.

Mounted on the shaft 23 within the subcompartment Chas shown in Figure 2is a fan or pump device 25 received within a suitable casing 26, which has an opening 27 at the side and a passage 28 projecting through the rear wall 11.

A similar pump or fan 25a is mounted ony the shaft 23 in the sub-compartment Cain a similar casing-26a. The casing 26a is provided with a side opening 27a and a rear outlet passage 28a similar to the opening 27 and passage 28.

In the sub-compartment C2, there is mounted on the shaft 23 a similar fan or pump 29 in a casing 30, having an intake opening 3l at its side and having a passage 32 extending upwardly through the partition 20 for the passage of air from the subcompartment C2 to the heater compartment In the compartment B, I provide a suitable heating element, which may consist of the steam coils 34. Y

In the compartment A is a oraminous cage or tumbler 35 supported on a shaft 36 mounted in boxings or bearings 37, as shown in Figure 4, .and having on one end outside the main casing a gearing device, such for instance'as the pulley 38.

The tumbler 35 is preferably made of a frame with screen wire or the like thereon and may be octagonal in cross section, as

shown in Figure 3.

It has an ordinary door 39 for permitting access to its interior. V

In the top l2 above the compartment A is an opening 40.

It will be noted that `the wall 18 terminates at its upper edge below the top 12, thus leaving an opening or passage between the compartments B and A.

Hingedly supported, as for instanceon the top 12, is a closure member 41 adapted to. be moved to `avariety of positlons, where it will close either the opening between .the compartments B and A or the one of the side walls 10 and has a handle 47 on its outer end.

Any suitable vdevice 48 may be provided for holding the handle 47 in different positlons of its adjustment.

The lower tapered portion of the comparti ment A has openings 49 for. providing communlcation between such compartment and the respective compartments C1 and C3. (See Figures l and 2.)

In the wall 17 opposite each opening 49 1s. an opening 50, as shown for instance in Figure 1, for which there is provided a sliding closure member 51, illustrated in Figures 1 and 3.

In the practical use of my improved drier, the clothes are put into .the tumbler 35 through the doors 16 and 39. The fans are' operated from some suitable source of power, and the tumbler isrotated.

Ordmarlly for the irst part of the drying process, the closure members 51 are closed,

the door 45 is opened, and the closure member 41 is moved to position for substantially closing the opening 40.V

Y The central fan or pump 29 will draw air through the passage 33 and the opening 3l inV the side of the :tan casing, and discharge the air through the passage 32 forcing it'through the compartment B, around the heating coils 34 through the opening between the partition 18 and the ,top 12 into the tumbler compartment A.

The fans or pumps 25 and 25 cause suction in the lower part of the compartment A and draw the air through the openings 49 into the compartment C1 and C3 and through the fan casings 26 and 26 for dis charging it through the passages 52, which may be connected with the outside of the building or otherwise, as may be desired.

My improved tumbler has a number of advantageous features of construction forming desirable functions.

By Yusing both blower and suction fans, I am enabled to maintain the air in the tumbler as nearly at atmospheric pressure as possible.

I find this desirable because it dries the clothes by contact with moving air, leaving the clothes in natural condition instead of compartment and discharged at any therein communicating with the tumbler coml.baking them as is done where a pressure pump only is em loyed.

By providin t 1e suction fans and blower fan as herein s iown and arranging the open-y of the'tumbler casingis tapered, as shown,`

and the openings are arranged, as disclosed in the drawings, we find that the lint is readily and easily drawn from the tumbler compartment, so that the device remains as eilicient so far as lint is concerned at the end of the'year as it is at the beginning.

The lint is simply drawn from the tumbler suitable point.

There is an advantage in the octagonal cylinder here shown over a round cylinder in that the clothes are truly tumbled with a rather gentle movement instead of being dropped a considerable distance or, beat. The buttons are not broken and the clothes are taken out in natural condition soft and loose.

Some changes may be made inthe construction and arrangement of the Vvarlous parts of my `drier, Without departing from the essential features and purposes of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.
